{install|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag. Lots of cleanup: - moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's described in the BeBook (although it's probably not really used that often :)) - int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone); it's now entirely handled in the arch/x86/ section. - the io_vectors[] is now statically initialized, instead of allocated from the heap - removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init() is now calling install_io_interrupt_handler() correctly instead - introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only (though on x86, it also has ARCH_INTERRUPT_BASE == 0x20). - changed the return type from {install|remove}_io_interrupt_handler() from "long" to "status_t" - rearranged and cleaned the PIC initialization code, made the PIC code more prominent - changed comments that talk about a non existing 8239 (the PIC chip is actually 8259) - moved arch/x86/interrupts.h to the source directory, as it's not used outside - added BeOS compatible interrupts_enabled() function, that should replace our equivalent (and private) are_interrupts_enabled() git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12477 a95241bf-73f2-0310-859d-f6bbb57e9c96
